lApplication led February 13,'1914. Serial No. 818,510.

To all 'wh-0m it may concern:

Be it'known that 1, GEORGE SEAUH, a subject of the Emperor of Austria-Hungary, residing at Dubois, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements j in Antiskid Devices, of which the following is a specification.. j

'lhis invention relates to improvements in non-skidding devices for automobile tires.

The primary object of lthe invention is the provision of positive means readily'v asof a tire, and as easilyremoved therefrom, which will give a positive traction grip to the wheel, thus preventing any'possible side slipping or skidding ofthe vehicle.

A further object is to provide a removable tire armor in several sections, each of which is clamped to the wheel while the sections are assembled with leverage clamping devices positioned therebetween.

A. still further object is to provide a tire armor which substantially incloses the entire tread portion of the tire and provides a traction surface therefor composed entirely of metal and is locked together and to the wheel by separate transverse and longitudinal :leverage clamping hasps. j

With these general objects in view and others that will appear as the nature of the invention isbetter understood, the same consists in the novel combination and arrangement' ,of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views Figure 1 is a side elevation of a portion of a tire with the present device assembled thereon. Fig. 2 is a transverse sectional view taken upon line 2-2 of Fig. 1. Fig. 3 tread plates detached. `Fig. 4 is a perspective view of one ofthe side bands showing the hasp clamping lever thereof. Fig. 5 1s a perspective view of onel of' the transverse hasps, and, Fig. 6 is a longitudinal sectional view through the adjacent ends of two side bands and illustrating the operation of the lever clamping hasp. 1

Referring more in detail to the'drawings,

it is to be noted that while the present device is employable upon the periphery of any 'form of wheel to prevent all slipping thereof and to insure the best traction properties, the invention is herein illustrated as mounted upon a pneumatic tire 10 posi 60 tioned within the usual clencher rim 11 upon a wooden felly 12. Y

The vsepara-te arch-shaped tread plates '13 are adapted to span the tread portion of the tire 10 and each has a desired number of studs 14 projecting from the outer convex surface thereof vwhile an outwardly projecting flange 15 is positioned at the ends of each plate for allowing the adjacent plates togabut thereagainst as best shown in Fig. 1.

Side bands 16 preferably eight in number, are adapted for arrangement circumferentially of the wheel and positioned against the opposite outer faces of the felly 12.

The band 16 has a plurality of upwardlyextending arms 17 having overturned tops 18 for rigidly mounting therein the pintles' 19 and being similar to the leaf and pintle of a hinge formation. The tread plates 13 80 have oppositely and 'downwardly extending arms 20, the ends of which are inturned as at 21around the pintles 19 in a grasping lhinged relation It will be notedthat while the side bands 85 16 vare preferably provided four in number upon `each side of the wheel, although a greater or less number of the same may be employed if desired, the tread plates 13 are of a much less length so that a plurality of said platesl are hinged to a single side band upon each side thereof.

The adaptation of said plates hinged to the opposite bands to seat upon the tire is believed to be apparent from the drawings as well as the serviceability of thedevice by reason of the {ieXibility of all of the connections and contact points.

In retaining the 4sections or the non-skid member upon lthe wheel, transverse hasps 22 100 are provided linked at alining points upon, the outer faces of the opposite side bands by suitable staples 23. Said hasps are provided in pairs, one of each pair having an upstanding perforated lug or staple 24 ad- 105 jacent the end thereof and adapted for re `ception through a receiving slot or eyelet 25 adjacent the end of the coperating hasp and whereby the two hasps may be joined an'd locked by the insertion of a locking 110 member such as the Cotter 26 through this eye 27 of the lug 24. This mounting of the plates and side bands around the tire and securing the same by the transverse hasp locks requires a further locking member for retaining the entire structure now consisting of the fourseparate parts, andl of which the four pairs of side bands form the base. For this purpose, each side band having an outwardly projecting end flange 28- adapted to abut with the similar flange of the adjacent band has a strap 29 hinged thereto by means of the block 30. The free end of each strap is provided with a lever 31 pivoted thereto while one end of said lever has the slot or eye 32 adapted to receive the staple 3 mounted upon the adjacent side band and after the manner of a hasp' formation vand being also provided withV a Cotter pin34 to retain the leverl end upon such staple.

The pivot point 35 of said lever is removed from both ends thereof and provides a short end 36 opposite to its slotted end while said short end terminates in an 11pturned flange 37.

With the tread plates and side bands properly assembled uponthe tire, and with tlie hasp 22 secured in place by their cotter pins, the adjacent. ends of the separate sections will be slightly separated, leaving the flanges 28 a short distance movement of the lever 31 as shown in Fig. 6, will position the end flange `,37 of the short arm thereof in contact with the end flange 28 of the adjacent side band and thus by a downward closing movement. of the lever for engaging its .slot with the staple 33, results in a suitable leverage for forcing-the two plates 16 toward and in contact with each other with their end flanges 28 in proper abutment as Well 15 of the carried tread retaining bands made segments',

apart' so that a as with the ilangesl plates also inv engagement.

The complete operation both of placing the device upon the wheel as well as quickly and readily removing the same therefrom will be at once apparent, while it is also to be understood that changes may be made in the form of the device as well as the material employed which however is preferably metal, Without departing from the spirit ,and scope of the invention.

IVhat I claim as new, is l. A tire armor comprising circular side up of segments having terminal flanges, armor sections secured to each pair of segments, and flanges on said sections radially alined with those of the and means for forcing the flanges of the segments into abutting relation.

2. AD tire armor comprising circular sideretaining bands'made up of scgmentsha-ving terminal iianges, armor sections secured to each pair of segments by a connection fiexi- A ble only in the plane of the wheel, and means for forcing the flanges of the segments into abutting relation.

3. A tire armor comprising circular sideretaining bands made up of segments having;r terminal flanges, armor sections secured to each pair of segments having radial bearing faces alined with the flanges, and means for forcing the flanges of the segments intov abutting relation.

In testimony whereof I affix my signature in presence of two Witnesses.
